Post subject:  R 7.1 Nvidia segfault - solved
I, like several people, am having the segfault issue with 2 of my frontend machines and am trying to downgrade the nvidia driver to 280.13 (a stable release). I have installed mercurial, gcc, and make - need linhes headers. Can someone please provide instructions to download headers for 7.1? Thanks.

to get just the headers:

Code:
sudo pacman -Sy kernel26-headers


or better yet, to get everything you need to build your own packages:

Code:
sudo pacman -Sy base-devel

Thanks Martian. For anybody else having the segfault issue, the 280.13 seems to have fixed the issue (so far)... The following is a simple method to back-rev the Nvidia driver.

Download Nvidia drivers (http://www.nvidia.com/Download/index.aspx?lang=en-us)

sudo pacman –Sy mercurial
sudo pacman –Sy gcc
sudo pacman –Sy make
(or if you want all pkgb build stuff - sudo pacman -Sy base-devel)

sudo pacman -Sy kernel26-headers

sv stop frontend

sh NVIDIA-Linux-x86-280.13.run
and follow scripts... Reboot.

I was having the stability problems so I follow the instructions. Looks like it downloaded a new version -- 290.10. I ran the script and now I am stuck in 640x480. Xorg.0.log contains the following:
Code:
[    26.666] (WW) NVIDIA(GPU-0): The EDID read for display device DFP-0 is inva\
lid: the
[    26.666] (WW) NVIDIA(GPU-0):     checksum for EDID version 1 is invalid.



Has anyone else seen anything like this? Any ideas? Thanks!

I download & installed 280.13 -- same problem with EDID not being read and being stuck at 640x480.

Question: I am running this via a remote putty window, not on the console. Could this cause any problems?

Did you allow the script to recreate xorg.conf? Or are you running your old xorg?

FYI - I ran mine from an SSH window - no problem.

First time through on 290.10 I told it not to re-create xorg.conf. Had the problems. Second time through on 290.10 I answered yes and I still had problems. Third time through on 283.13 I answer yes and still had the same problem of being locked into 640x480, but the seg faults stopped happening.

I then hand-edited xorg.conf and essentially replaced it with the contents of an xorg.conf I had hanging around from R6.04 and I was able to get all my resolutions again. I've posted my xorg.conf below -- would someone mind posting the xorg.conf they get from their R7 system that is working properly? I'd like to diff them.

Quick update. I have discovered that the keyboard connected to the computer no longer works. /var/log/Xorg.conf.log contains the following error:
Code:
[ 72691.859] (EE) Failed to load module "kbd" (module does not exist, 0)


Any ideas on how to resolve this would be appreciated.

Thanks for posting that. Unfortunately, I have the same keyboard problem. I just used "pacman -S xf86-input-keyboard" and "pacman -S xf86-input-mouse". I no longer have errors my my Xorg logs. I'm not near the machine right now -- will check the keyboard when I get home.

I was having the same issues after upgrading to 7.1. On boot, keyboard is not responding, also getting the kbd errors in Xorg.0.log. The
Code:
pacman -Sy xf86-input-mouse xf86-input-keyboard

fixed it for me.
